Operating instruction：
1. Buttons define：ON、Psi/atm
2. Startup & Shutdown define：Standby mode press ON then boot, in boot state long press ON for about 5s to turn it off and ON the pressure change, automatic shutdown to enter standby mode.
3. Backlight define: in the boot state, press any key backlight, 10 seconds backlight off no pressure change.
4. Unit conversion define，in the boot state，press psi/atm key，unit changed from psi and atm（note：atm is 1 atmosphere，means 1Kg/mm2）
5. Reset function set ：in the boot and gauge pressure is 0.0atm，press psi/atm key about 5s，pressure gauge will  auto display“000”zero reset，but not recorded in the register, turn it off when they will return  to the factory default  .
6. Outrange warning function define： when measuring the pressure gauge is greater than the range of 1.1 times the outrange alarm appeared "Err" character, bad pressure is 2 times the rated range.
7. Power supply ：internal and external power supply function ,internal is 3VDC battery  supply（230mA/h），external is 5~15VDC power supply.
